To all iv/tom arm concern: Be it linown that l, Jot-int U. l-lniuzn, a pcitizen or the United hltates, residing at Lakeland, in the county ofFolk and latate of Florida, have inventedcertain new and usefulImprovements in Lathe 'Fools, of a which the tollowing is. a,specification.

y said invention relates to a lathe tool primarily intended for metalworking machinery and it is an object thereof to pro vide a singleholding device which shall be adapted to support in working position anyone or the tools ordinarily used in a lathe oi? this character;

it. further object of the it invention is to a lathe tool a proved meanscutting tool. a I

deterring to the accompanying drawlngs which are made apart hereof andon which similar reference characters indicate similar parts,

Figure l is a perspective of my lathe tool, Figure l, a front elevationof the same, Figure 2, a plan view on a reduced scale showing acutting-oil tool held thereby,

Figure 3 a view similar to Figure 2 show ttlt ltd-- thereon, a

Figure 4 a similar view showlng a righthand cutting tool in place,

Figure 5 a plan showing the boring bar in working position on the lathetool, and Figure 6 a detail of the tool-holding end at the boring bar,parts being broken away to show the inner structure.

he the drawings 10 indica oil the lathe tool having a biturcatedhead ll,the horizontal slot 12 terminating in a cylindrical opening 13 and beingintersected by a clamping screw It for drawing together the two sides toclamp the various tools in place, it. boring bar 15 (F igs. 5 and t) isadapted to be inserted in the opening .ltl and the outer extremityoztthe lathe tool isitormed with a plurality of clamping laces torholding various cutters and the like, these laces being formed bycutting away portions ot" the head. indicated at 16 are intended forholding a cutting oflt blade 1? (Fig. 2) or a racing tool or the lilre.'llhe opposed faces 18, 18 are l adapted to hold a right-hand cuttingblade tes the shank 'tlll Ut these tacos those l will. lterial lilo.t'lddlltl.

19. A. similar pair ct faces 20, 20. at the opposite side oi?" the headare adapted to hold aloft-hand cutting tool 21.

boring tool is shown in Figure 5 having abar 15 setin the opening 13 otthe lathe tool 10.. A. red 23 passes through the holder and has atoneend a screw for en gageinent by a nut 24- and at theother end intotwo lorlrs 25 to embrace a boring tool 26. .lt will be seen that the rodmay be moved by rotation oi the nut to lock or release the tool 25; ltwill be evident that practically any tool of ordinary use in a lathe maybe held in working position by the use of my device. or example aninternal threading tool may e substituted for the boring tool 25, (Fig.

lades of Figures 3 and t.

lt will also be evident to those skilled in the art that my device maybe modified in various ways Without departing from the spirit of theinvention nor t e scope of the appended claims. Therefore ll do notlimit myself to this specific device shown in the drawings and describedin the specification but only as indicated in said claims.

'laving thus fully described my vention, what it claim as new and desireto Patent, is: athe tool comprising a shank, a head thereon, said headbeing bifurcated, means for drawing together the sides of th t eopposing faces of such sides formed to engage directly with and to inplace a cylindrical bor' lades of various widths set forth.

said in being bold ng bar or cutting substantially as receive a toolholder, an at the other side of the cutting away aces being ad posedlaces formed by head, said it screw portions of the apted to holdcutting blades, substantially as set forth.

3. ll lathe tool comprising a shank, a split l, a transverse screw fordrawing the or" the head together, a cylindrical opening between thesaid sides, a hollow cylindrical bar lined in said opening, a rodconcentric with said bar and having one end e head,

hli

llltl formed to engage a tool, and a nut at the other end toimpart,longitudinaljmovement head together and means on said headzrfon'directly engaging and holding alternativel a cylindrical boring bar, acutting-off too 10 a right-hand cutting tool and a left-hand cuttingtool; substantiallyas set forth.

head, means for drawing the sides of; the head together and means onsaid head for 15' directly engaging and holding alternativelyacylindrical boring bar, and cuttingtoqls with rectangular holdingportions, substan-' tially asisetiforth.

means for drawing 25 g the forks of the head together, substantially asset forth.

In witness whereof, I have hereunto, set of Columbia, thisZSth-day 0May, A. D. 8 nineteen hundred and twenty-one.
